Sedation and analgesia is an essential part of the emergency work. Presently, for adults, clinical assessment and application of sedation and analgesia has been gradually perfect, but in the face of pediatric patients, clinicians would always concern drug-related adverse reactions as well as a variety of uncontrollable factors, leading to reducing and even ignoring the sedation and analgesia in children. This review focuses on the current research status and relevant evidence of pediatric sedation depth and risk assessment, pain assessment, as well as the principles, application methods, advantages and disadvantages of various commonly used clinical drugs, and the aim is to provide evidence for higher quality sedation and analgesia for children.
Objective To establish and verify the early prediction model of critical illness patients with influenza. Methods Critical illness patients with influenza who diagnosed with influenza in the emergency departments from West China Hospital of Sichuan University, Shangjin Hospital of West China Hospital of Sichuan University, and Panzhihua Central Hospital between January 1, 2017 and June 30, 2020 were selected. According to K-fold cross validation method, 70% of patients were randomly assigned to the model group, and 30% of patients were assigned to the model verification group. The patients in the model group and the model verification group were divided into the critical illness group and the non-critical illness group, respectively. Based on the modified National Early Warning Score (MEWS) and the Simplified British Thoracic Society Score (confusion, uremia, respiratory, BP, age 65 years, CRB-65 score), a critical illness influenza early prediction model was constructed and its accuracy was evaluated. Results A total of 612 patients were included. Among them, there were 427 cases in the model group and 185 cases in the model verification group. In the model group, there were 304 cases of non-critical illness and 123 cases of critical illness. In the model verification group, there were 152 cases of non-critical illness and 33 cases of critical illness. The results of binary logistic regression analysis showed that age, hypertension, the number of days between the onset of symptoms and presentation at the emergency department, consciousness state, white blood cell count, and lymphocyte count, oxygen saturation of blood were the independent risk factors for critical illness influenza. Based on these 7 risk factors, an early prediction model for critical illness influenza was established. The correct percentages of the model for non-critical illness and critical illness patients were 95.4% and 77.2%, respectively, with an overall correct prediction percentage of 90.2%. The results of the receiver operator characteristic curve showed that the sensitivity and specificity of the early prediction model for critical illness influenza in predicting critical illness patients were 0.909, 0.921, and the area under the curve and its 95% confidence interval were 0.931 (0.860, 0.999). The sensitivity, specificity, and area under the curve (0.935, 0.865, 0.942) of the early prediction model for critical illness influenza were higher than those of MEWS (0.642, 0.595, 0.536) and CRB-65 (0.628, 0.862, 0.703). Conclusions The conclusion is that age, hypertension, the number of days between the onset of symptoms and presentation at the emergency department, consciousness, oxygen saturation, white blood cell count, and absolute lymphocyte count are independent risk factors for predicting severe influenza cases. The early prediction model for critical illness patients with influenza has high accuracy in predicting severe influenza cases, and its predictive value and accuracy are superior to those of the MEWS score and CRB-65 score.
Objective To investigate a new way for the treatment of severe acute pancreatitis (SAP). Methods The clinical data of 59 cases of SAP were analyzed, and they were divided into two groups: LAI group and control group. In LAI group, 30 cases were treated mainly by local arterial infusion (LAI). In control group, 29 cases were treated by intravenous infusion. Results Compared with control group, the results of LAI group were much better in abdominal pain relief, recovery of intestinal function, reducing the complications, shorter antibiotictime, decreasing the incidence of secondary systemic infection. The mortality of SAP class Ⅱ in LAI group and control group were 35.71% and 66.67% respectively. Conclusion LAI is a new way for the treatment of SAP.
Objective To introduce the total mesorectal excision (TME)under the laparoscope and with the ultrosonic scalpel. Methods Under the laparoscope and with the ultrosonic scalpel, total mesorectal excision in 3 patients was performed. In operation, alone the parietal layer of pelvic fascia and inside the automatic nerve trunk, the mesorectum was excised with the ultrasonic scalpel. Results Three patients got final recovery, no damage to the viscera in operation occurred. Average hemorrhage amount was about 100ml. Intestinal function recovered within 24 hours, average in hospital time was 10.3 days. After 4 months, 3 patients got good living quality without recurrence and metastasis.Conclusion TME under the laparoscope is a new progress of less damageable operation. Compared with the traditional open laparotomy,it has some advantage. But it requires high technology and expensive equipments, and the case is still very limited in use.
In recent years, with the development of ultrasound technology, pulmonary ultrasound is more and more used in the evaluation of patients with heart failure. B-lines are defined as reverberation artifacts starting from the pleural line and extending to the bottom of the screen without disappearing, and moving synchronously with pleural sliding, which are proportional to extravascular lung water in congestive heart failure (CHF). B-lines have the characteristics of no attenuation and synchronous movement with pleural sliding. Pulmonary ultrasound mainly record the numbers and widths of B-lines in the areas when assessing the severity of CHF, which have the characteristics of effectivity, non-invasiveness, instantaneousness, and good repeatability. Currently, there are 4-, 8-, 12-, and 28-subdivision methods for the evaluation of CHF in the pulmonary ultrasound subdivision method. The more subdivisions are, the longer the operation time will be, and the sensitivity and specificity will be different. How to choose a subdivision method is still controversial in clinical practice. Lung ultrasound could be used alone or combined with brain natriuretic peptide, echocardiography, chest X-ray, chest CT scan, etc. in the early diagnosis, assessment of disease severity, evaluation of efficacy, and assessment of prognosis of CHF, with different advantages and disadvantages. This article reviews the application and progress of pulmonary ultrasound in CHF.
Hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) has the characteristics of rapid progress and high mortality. Artificial liver support system (ALSS) is far superior to standard drug therapy in the treatment of such patients, and is widely used in emergency. ALSS is the use of external mechanical or biological devices to replace a part of the damaged liver function, divided into bioartificial, non-bioartificial liver and a combination of the two. At present, there is no unified sensitive prognostic index and recognized prognostic model for HBV-ACLF in artificial liver treatment. This paper reviews the research progress of prognosis evaluation of ALSS in the treatment of HBV-ACLF, in order to provide reference for clinicians and researchers
Objective To summarize the clinical therapeutic efficacy of emergent laparoscopic cholecystectomy （LC） and emergent open cholecystectomy （OC）. Methods One hundred and thirty-three patients with acute cholecystitis from March 2011 to June 2012 in this hospital were randomly divided into emergent LC （ELC） group and emergent OC （EOC） group. The examination and treatment before and after operation were the same. The clinical data before and during operation， postoperative complications， and recovery conditions were observed and compared. Results There was no obvious difference of the clinical data before operation between the ELC group and EOC group （P＞0.05）. Also， there were no significant differences of the operation time， biliary duct injury rate， postoperative bleeding rate， and reoperation rate in two groups （P＞0.05）. The time of postoperative anal exsufflation， time of out-of-bed activity， and postoperative hospital stay in the ELC group were significantly shorter than those in the EOC group （P＜0.05）， the poor incision healing rate in the ELC group was significantly lower than that in the EOC group （P＜0.05）， and the intraoperative blood loss in the ELC group was significantly less than that in the EOC group （P＜0.05）. Conclusions ELC as compared with EOC， are less intraoperative blood loss， less postoperative complications， more rapid recovery， and do not increase operation time. In a hospital with skilled LC technique， ELC is safe and feasible， has obvious advantages of minimal invasion.
Objective To investigate the efficacy of systemic immune inflammation index (SII) at admission and National Institutes of Health Stroke Scale (NIHSS) score immediately after thrombolysis on evaluating the short-term prognosis of neurological function in patients with acute ischemic stroke (AIS) receiving intravenous thrombolysis. Methods Patients with AIS treated with intravenous thrombolysis in the Second People’s Hospital of Chengdu between March 2022 and March 2023 were retrospectively analyzed. The basic data of the patients, NIHSS score at emergency admission, NIHSS score immediately after thrombolysis, modified Rankin Scale (mRS) score 3 months after discharge, and laboratory data at admission were collected, and SII at admission was calculated. According to the mRS score 3 months after discharge, the patients were divided into the good prognosis group (mRS≤2) and the poor prognosis group (mRS>2). Multivariate logistic regression analysis was used to screen out the factors affecting the prognosis of patients, and the receiver operating characteristic curve was drawn to analyze the evaluation effect of SII at admission and NIHSS score immediately after thrombolysis on the poor prognosis of neurological function of patients in the short term. Results A total of 213 patients were enrolled, and the prognosis was poor in 88 patients. Multivariate logistic regression analysis showed that age, onset-to-needle time, uric acid at admission, SII at admission, fasting blood glucose after admission, and NIHSS score immediately after thrombolysis were independent risk factors for poor prognosis in AIS patients (P<0.05). The area under the receiver operating characteristic curve (AUC) of SII at admission for predicting poor prognosis was 0.715, the sensitivity was 55.7%, and the specificity was 84.0%. The AUC of NIHSS score immediately after thrombolysis for predicting poor prognosis of patients was 0.866, the sensitivity was 87.5%, and the specificity was 72.8%. The AUC of SII at admission combined with NIHSS score immediately after thrombolysis for predicting poor prognosis of patients was 0.875, the sensitivity was 84.1%, the specificity was 77.6%, the positive predictive value was 72.5%, and the negative predictive value was 87.4%. SII at admission was positively correlated with NIHSS score at emergency admission, NIHSS score immediately after thrombolysis, and mRS score 3 months after discharge (P<0.05). Conclusion SII at admission can predict the short-term prognosis of neurological function of patients with AIS after thrombolysis therapy, and the combination of SII at admission and NIHSS score immediately after thrombolysis can improve the prediction efficiency.
Objective To evaluate the clinical effectiveness of laparoscopic and open appendectomy. Methods Literatures relating to randomized controlled trials in English and Chinese on the comparison of clinical effectiveness after laparoscopic and open appendectomy in appendicitis from PubMed，Wiley Online Library，Medline，Embase，Cochrane，CNKI，VIP，CBM databases were extracted，and methodological quality was evaluated by two reviewers independently with designed extraction form. The Cochrane Collaboration’s RevMan 4.2.2 software was used for data analysis. The wound infection，hospitalization time，operation time，hospitalization expenses，and peritoneal abscess were compared between laparoscopic and open appendectomy. Results Eight published reports of eligible studies were extracted. Compared with the open appendectomy， laparoscopic appendectomy had significant differences in lower wound infection rate 〔OR=0.19，95%CI （0.09，0.38），P＜0.000 01〕， longer operation time 〔WMD=3.66，95%CI （0.50，6.82），P=0.02〕，and more hospitalization expenses〔WMD=503.96，95%CI （337.23，670.70），P＜0.000 01〕.But there were no significant differences in hospitalization time〔WMD=-0.11，95%CI （-3.64，3.43），P=0.95〕 and incidence rate of peritoneal abscess 〔OR=1.40，95%CI （0.23，8.64），P=0.71〕 between laparoscopic and open appendectomy. Conclusions The wound infection rate is lower，but the operation time is longer，the hospitalization expenses is more in laparoscopic appendectomy as compared with open appendectomy. There are no statistically significant differences of hospitalization time and incidence rate of abdominal abscess between laparoscopic and open appendectomy.
Objective To investigate the method of the treatment on cholecystolithiasis combined with calculus of common bile duct (CBD) by laparoscopy with combination of choledochoscope and duodenoscope and its significances. Methods Forty-two patients with cholecystolithiasis combined with calculus of CBD were treated by laparoscopy with combination of choledochoscope and duodenoscope from Jan. 2007 to Dec. 2008 in this hospital. Under general anesthesia, laparoscopic cholecystectomy was performed first, then the anterior wall of CBD was opened, calculus of CBD was treated by choledochoscope and duodenoscope intraoperatively. Then primary suture of the CBD was performed under laparoscope and nasobiliary drainage duct was placed. Results One case was converted to laparotomy, 41 cases succeeded and left hospital after being taken off the nasobiliary drainage duct in 5-7 d. No case died, no bile leakage, no bleeding or perforation of upper digestive tract, and no acute pancreatitis happened after operation. Conclusion Laparoscopy with combination of choledochoscope and duodenoscope treating cholecystolithiasis combined with calculus of CBD is a safe, effective and quickly recovering method with less sufferings and trauma.
